A bond fund pools investor capital to hold bonds and other debt securities, exposing shareholders to portfolio income, credit, duration, and market risk.
A bond fund, also called a debt fund or fixed-income fund, is an investment fund that primarily holds bonds and other debt securities. Unlike a single conventional bond, a bond fund usually has no maturity date at which an investor is promised a fixed principal amount.
| Type | Main exposure | Important risk |
|---|---|---|
| Government bond fund | Sovereign or agency debt | Interest-rate, inflation, and sometimes sovereign risk |
| Corporate bond fund | Company debt | Credit spread and default risk |
| Municipal bond fund | State and local public debt | Credit, call, liquidity, and tax-treatment risk |
| Asset-backed fund | Securitized receivables or loans | Prepayment, structure, model, and collateral risk |
| Floating-rate fund | Variable-rate debt and often below-investment-grade loans | Credit and liquidity risk remain despite lower rate sensitivity |
| Inflation-linked fund | Inflation-indexed government or other debt | Real-yield duration and index-mechanics risk |
| Bond index fund | Portfolio designed to track a bond index | Tracking difference and index-construction risk |
A fund with an effective duration of six years would be expected, as a rough first-order estimate, to lose about 6% if relevant yields rose by one percentage point, before considering convexity, spread changes, income, fees, and portfolio trading. Duration is a sensitivity estimate, not a guaranteed forecast.
| Feature | Bond fund | Individual conventional bond |
|---|---|---|
| Maturity | Fund usually operates continuously | Has a stated maturity date |
| Principal | Share value fluctuates; no standard par repayment to the shareholder | Issuer promises par repayment subject to default and terms |
| Diversification | May hold many issuers and maturities | Exposure depends on selected bonds |
| Cash flow | Distributions vary with portfolio income and policy | Coupon and principal schedule defined by the bond terms |
| Trading | Mutual-fund NAV or exchange price for ETF shares | Dealer or exchange market depending on instrument |
Review the mandate, benchmark, effective duration, maturity profile, yield measure, credit-quality distribution, sector and issuer concentration, derivatives, leverage, currency hedging, turnover, liquidity, fees, distribution policy, and historical stress behavior. Compare SEC yield, distribution yield, yield to maturity, and trailing income only after confirming how each is calculated.
